Carbon Fiber Processing: A Detailed Guide
Fabricating carbon fiber parts involves a intricate series of steps, commencing with the precursor. Typically, this precursor is PAN , which is stretched into small filaments. These strands are then stabilized at significant temperatures to improve their heat resistance, followed by pyrolysis in an inert atmosphere. This graphitization process transforms the polymer structure into nearly pure carbon. Subsequently, the resulting carbon filaments are often sized with a bonding agent to boost their bonding to a composite material, typically an epoxy resin, during the final component creation. The final step includes different methods like layup and setting to achieve the specific form and mechanical properties.
